IMPROVEMENT IN PORTABLE SOLDERlNG-FURNACE.

Specification forming part of Letters Patent No. 90,724,`datcd June l, 1869.

To all whom 'it lmay concern:

Be it known that I, JosIAH BURGEss, of Zanesville, in the county of Muskingum and State of Ohio, have invented a new andl Improved Soldering-Iron Heater; and I do here- -by declare that the following is a full, clear,

and exact descriptionthereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of vthis speciication.

This invention relates to improvements in furnaces for heating soldering-irons, designed to provide an apparatus forv the employment of naphtha and other products of petroleumoil for generating the heat.

The invention consists in the construction of the furnace hereinafter described, adapted to be used in combination with the naphthaburner, for the purpose of heating solderingirons.

Figure 1 represents a longitudinal sectional elevation of my improved apparatus, and Fig. 2 represents a transverse section of the same.

Similar letters of reference indicate corresponding parts.

A represents a burner for naphtha or other products of crude petroleum, such as now in common use.

To the longitudinal tube B of the burner I secure the base O of a soldering-iron furnace, preferably of a circular form. The said base is provided with an opening along the tube, each way from the point above the burner, designed to admit the flame after impinging upon the tube; and projecting downward from the said opening are two lips, D, for preventing the spreading of the flame.

After passing above the base C the ilame encounters a curved hood, E, running transversely of the base from an opening, F, in the vertical wall ofthe furnace. This hood spreads the flame in each direction, and imparts to it the proper shape to envelop the Whole length of the soldering-iron, which is inserted at the opening F.

From the hood the flame passes off at each end into a space, G, inclosed by the vertical walls and the top H., whereby the heat is prevented, to a great extent, from escaping from the hood or heating-space. From the space G the products of combustion pass oft' through holes in the top H.

By the employment of fuel of this character the volume of flame and heat may be regulated to such a degree that the irons may not be heated too much, as is new the case when using coal, whereby the tin is burned off the iron. Moreover, the vapor of Water carried up .into the flame from the reservoir, always used with these burners, makes a soft and Vpleasant heat, and the noxious vapor arising from charcoal is avoided. .The flame may always be sluit down or off entirely, when required, for economy.

Having thus described my invention, I el aim as nenT and desire to secure by Letters Patent- The soldering furnace constructed, as de scribed, of the case C, having its slotted bottom provided with lips D, the hood E, and the perforated top H, arranged with the burnerA and tube B, as herein set forth, for the purpose specified.
